Mr. Blonde's real name is Vic Vega.  John Travolta plays Vincent Vega in Pulp Fiction. In a cut scene, Nice Guy Eddie (Christopher Penn) is calling a doctor to fix Mr. Orange.  Her name is Bonnie.  Quentin Tarantino's wife's name is Bonnie in Pulp Fiction.  And she's a nurse.  Mr. Blonde's parole officer is Seymour Scagnetti. Scagnetti plays the cop in Natural Born Killers. Mr. White used to hang out with Alabama. Alabama is the lead female in True Romance.

In the opening scene of Reservoir Dogs Quentin Tarantino says that Madonna's "Like a Virgin" song is a metaphor for big dicks. Long after the movie was made, Quentin met Madonna and she gave him a copy of her album Erotica and inscribed it with "To Quentin - it's about love, not dick."

Mr. Blonde's car really belonged to Michael Madsen. The film's budget restricted Quentin Tarantino from buying a separate car for the Blonde character.

Eddie Bunker, who played Mr. Blue, is a career criminal and sometime actor. His autobiography, "Dog Eat Dog", on which Reservoir Dogs is partly based, is one of Quentin Tarantino's favorites, and the namesake for his production company, Dog Eat Dog Productions. This is why QT cast him in the movie, despite his having no dialogue and not contributing to the plot in any way other than being the first to die.

Quentin Tarantino did not actually give a script to Kirk Baltz (Marvin Nash) for the scene in which Mr. Blonde was going to light him on fire. Instead, while practicing the scene, he basically just said "Convince this man not to light you on fire." While Kirk Baltz was going through the obvious lines like "Please don't. Stop.", he remembered Michael Madsen had just had a kid, and said "I have a little kid at home." As soon as he said that, Madsen immediately stopped, and did everything he could to convince Quentin to NOT let Baltz use that line, but Quentin liked it so much he made him use it for filming.

Not really a mistake, just an observation.  At the end of the movie when Joe appears, he is asked the status of one of the other crooks.  He replies, "Dead as Dillinger".  The actor who plays Joe, Lawrence Tierney, portrayed Dillinger in the 1945 Monogram film 'Dillinger'.

There are two Wilhelm Screams in the movie. One is when Mr. Brown is shot. The second is when Mr. Pink pushes someone out of the way when running from the cops.

Michael Madsen (Mr. Blonde/Vic Vega) was scheduled to play the role again in Pulp Fiction (and apparently, if he had, Jules would have been the one who was killed in the bathroom through a completely different story...), but he couldn't due to commitments to the film Wyatt Earp. Quentin Tarantino was adamant to work with him again, however; keep an eye out for him in Kill Bill.

Kirk Baltz wanted to get the feel of what it was like to be driven around in a trunk, so one day on the set he asked Michael Madsen to drive him around for a while. Madsen immediately jumped at the opportunity and took him for a drive. He planned on taking a quick trip around the block, but decided to have some fun, and went down an extremely bumpy alley. When he got out of the alley, he saw a Taco Bell, and figured he should get some food, just like Mr. Blonde does in the movie. Madsen said that he had to turn the radio up really loud to make sure no one heard the screams that were coming from the trunk. Ask Michael Madsen, and when he opened the trunk, Baltz was terrified and crying like a baby. Ask Baltz, and he was a little shook up, but handled it well.

Tim Roth had to lie in his pool of blood for so long that it dried and stuck him to the floor, and he had to be peeled off. A similar event happened to Tom Noonan while filming "Manhunter" in 1985. Submitted by Cubs Fan

In the opening scene Tarantino is giving his interpretation of "Like a Virgin." Nice guy Eddie is played by Madonna's former brother-in-law (Chris Penn)

The film's budget was so low that many of the actors simply used their own clothing as wardrobe, most notably Chris Penn's track jacket. The signature black suits were provided for free by the designer agnes b., based on her love for the American crime film genre. Steve Buscemi wore his own black jeans instead of suit pants.

When Harvey Keitel and Steve Buscemi go to the back room of the warehouse, Keitel asks Buscemi for a cigarette. When he gives him the cigarette, Keitel leaves the scene for a brief moment. He in fact leaves the scene because he had forgotten the lighter and would not be able to light the cigarettes, but being a good actor, he just went with it left the scene got the lighter and came back to finish the scene.

When we see Eddie on his way to the warehouse there's a clue as to the rat's identity - an orange balloon behind the car. Submitted by Jon Sandys

Producer Lawrence Bender plays a young cop chasing Mr. Pink during his getaway.

In the opening scene at the diner when they are leaving, just before it fades to black, Nice Guy Eddie can be seen tripping over one of the chairs.

After Mr. Orange passes out, Mr. Pink and Mr. White go into the next room to talk.  On the counter is some white liquid and pink liquid next to each other and orange liquid on the other side of the counter.

Michael Madsen was extremely reluctant to film the torture scenes, especially when he was required to hit Kirk Baltz. Submitted by Cubs Fan

When Mr White and Mr Orange hijack a car, the driver, a woman, takes a gun and shoots Mr Orange, who shoots her back. That woman is Tim Roth's [Mr Orange] dialogue coach who trained him - a Brit - to speak with an American accent. Submitted by Ferdinand Y Wang

With reference to another bit of trivia that points out Michael Madsen's Vic Vega in this film and John Tratolta's Vincent Vega in "Pulp Fiction" (1994). They were written to be brothers.
